Title: Liquiddsteam separator
IPC: B04C3/00
Filed: 1977-11-24
Abstract: A centrifugal moisture separator for steam generators is used esp. for natural circulation steam generators of nuclear power plants and comprises a (vertical)cylindrical housing, a vortex chamber tapering conically in the direction of flow inside the housing and an inlet duct at the bottom with blades to impart a twist to the entering steam. The dried steam leaves the top of the housing and water centrifuged inside the vortex chamber is recirculated into the steam generator. The vortex chamber is a perforated venturi tube, comprising a conically tapering inlet portion and a conically diverging diffusor portion continuing as far as the vortex chamber outlet the centrifuged liquid phase and any solid particles contained in it is pressed through the perforations of the venturi tube into the annular space outside it and inside the housing, and is collected and removed from the bottom of this annular space. Used typically for a pressurised water reactor. The effect of the second, diverging portion of the vortex chamber or separator with perforations in the wall is to ensure that the separated water is projected righ outside the steam flow and therefore cannot be entrained by it again in the annular space outside the vortex chamber, the water can trickle unimpeded downwards on the outer wall collet at the bottom. Pressure drops are reduced and separation efficiency is increased.

Title: Solar energy type heater equipped with grading with solid heat trap
IPC: F24S10/75
Filed: 1978-08-11
Abstract: Solar heating system consists of a housing with a transparent front cover backed up by a heat trap. Below this is a flat collector element which will absorb solar radiation. A means is provided for allowing a heat transfer fluid to flow through this in tubes giving good heat transfer between the collector and the fluid. The combination of cover plate and heat trap form a single unit made from a transparent material which is opaque to re-emitted radiation from the collector. The trap is of cellular construction with vertical walls projecting from the flat cover surface. It is of a honeycomb type cross section. The length to dia. ratio should be 2-10 and has a wall thickness of 0.002-0.5 mm. The transparent cover is pref. made of glass or plastics, e.g. polyvinyl fluoride, polycarbonate, polymethylmethacrylate, PET or aromatic polyester. Used for recovery of solar energy. The use of traps is known with mounting rods and bonding to the front plate. The system described reduces the amount of scattered radiation from the surface to the unit, giving a trap with considerable rigidity, durable, easy to hand and economic to manufacture.

Patent ES-8400975-A1 (ES)
Title: Improved drive/guide system for a reciprocating floor conveyor.
IPC: B65G25/04
Filed: 1982-07-06
Abstract: Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1, 2, 3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (128, 130, 132) to which the cylinders (1, 2, 3) are connected. These beams (128, 130, 132) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (128, 130) which depends from an upper central portion of a transverse truss (80, 82). Each longitudinal drive member (128, 130, 132) is welded to a transverse drive beam (10, 12, 14) by fillet welds on each side of the longitudinal drive tube (128, 130, 132). Each such drive tube (128, 130, 132) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22). The guide beams (22) are small in size and are welded on both sides to transverse support beams (24). The construction of the slide bearings (26) permits the use of large dimension, strong, undressed fillet welds. The slide bearings (26) include wing portions (68) on each side which abut similar wing portions (68) on sideways adjacent bearings (26). The floor members (28) are held vertically relative to the bearings (26) by the engagement of bottom flanges (36, 38) within side slots (72) formed in the bearings (26). The floor members (28) add strength and stiffness to the bearings (26) and the abutting contact of the wing portions (68) causes the bearings (26) to mutually brace each other.

Title: Plastics material mesh structure.
IPC: B29D99/00
Filed: 1982-10-04
Abstract: In order to provide uniaxially-stretched and biaxially-stretched mesh structures which allow for different specific designs of the interconnecting strands, a special punching pattern is used to provide holes in the starting material. The starting material has a "square" pattern of large holes. Further holes are added. These further holes can be small holes which are staggered and in pairs. When the starting material is stretched, the uniaxially-stretched structure has transverse bars interconnected by highly orientated strands each of which forks at both ends into further highly orientated strands, providing a structure which is particularly suitable for soil reinforcement. When the structure is stretched in the direction at right angles to form a biaxially-stretched structure, the zones of the bars which are between aligned strands remain as unorientated or partly orientated junctions. The remaining zones of the bars are stretched out to form highly orientated strands. This biaxially-stretched structure is particularly suitable for soil stabilization.
